Oracle-Opal (1/4 lb)

Technical Opal

SKU: 11.84 Categories: ,


Oracle-Opal, a striking glass that produces a range of misty opal tones.  It easily resets to crystal clear, initiating the striking process.  After resetting, Oracle-Opal will cool to a faint translucent opalescence. Further exposure to flame temperatures around 1000°F will cause more extensive opacification.

For Best Results: If you’d like to retain the color effect as-is when you’re done, anneal cool at about 920°F for up to two hours. Higher temperatures and longer annealing times will initiate further striking of the opal.  Encasing the Opal will also add heat and time so adjust your annealing accordingly or plan on having more opacity.

The Bead: is a wigwag bead with Oracle Opal and Zephyr.

The Oracle Projectresponsibly manufactured, low toxicity glasses made in the USA, without Antimony, Arsenic, Cadmium, Chromium, Lead, Nickel, or Selenium. Balancing viscosity curves, opacity, tonality, surface tension, and thermal shock resistance, to create glass that is a pleasure to work with in the flame.
